Alzheimer's Disease: Overview

1.6K
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...

251
DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Imaging Studies IV: Magnetic Resonance Imaging

212
Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...

科学分野:

  • 神経科学; 老年医学; 公衆衛生

背景:

  • 低栄養は認知機能低下と関連していますが、非西洋圏の農村人口における研究は限られています。 多様な人口統計におけるこれらの関連を理解することは、世界の健康イニシアチブにとって重要です。

研究 の 目的:

  • 農村南インドのコホートにおける低栄養、認知パフォーマンス、および脳形態の関係を調査すること。 リスクのある個人を特定するための様々な栄養指標の有効性を評価すること。

主な方法:

  • CBR-SANSCOG研究から得られた3687人の非認知症成人(45歳以上)の横断的分析。 栄養状態は、高齢者栄養リスク指数(GNRI)、予後栄養指数(PNI)、栄養状態制御(CONUT)スコア、ボディマス指数(BMI)、および上腕中間囲(MUAC)を用いて評価されました。 認知機能は、ヒンディー語精神状態検査(HMSE)およびCOGNITOテストを用いて評価され、脳形態はサブセット(n=1150)でMRIを用いて分析されました。

主要な成果:

  • 参加者の8.8%から19%が、異なる指標に基づいて低栄養のリスクがありました。 GNRIは、標準複合指標(SCI)との間で最も良好な一致を示しました。 GNRI、BMI、MUAC、認知パフォーマンス、および脳形態との間に正の関連が見られました。 MUACは、BMIよりも認知領域との関連が強いことが示されました。

結論:

  • 高齢者栄養リスク指数(GNRI)は、認知パフォーマンスと脳構造を確実に予測します。 上腕中間囲(MUAC)は、認知機能障害のリスクのある農村インド人を特定するための、シンプルで費用対効果の高い指標です。
